 * Usage:
 * 
 * <pre>
 * java jena.examples.ontology.persistentOntology.Main
 *                  [--dbUser string]     e.g: --dbUser ijd
 *                  [--dbURL string]      e.g: --dbURL jdbc:postgresql://localhost/jenatest
 *                  [--dbPw string]       e.g: --dbPw nosecrets
 *                  [--dbType string]     e.g: --dbType PostgreSQL
 *                  [--dbDriver string]   e.g: --dbDriver org.postgresql.Driver
 *                  [--reload]            if true will reload the source data
 *                  [sourceURL]           optional source URL for the data to persist
 * </pre>
 * 
 * If no db parameters or source URL is given, defaults will be used.
